1 John 2:24-26

New Catholic Bible

²⁴ Let what you heard from the beginning
remain in you.
If what you heard from the beginning
remains in you,
then you will remain in the Son
    and in the Father
²⁵ And this is the promise he made to us:
eternal life.
²⁶ I write these things to you
in reference to those
who seek to lead you astray.
